A primary source is a document, speech, or other sort of evidence written, created or otherwise produced during the time under study. Primary sources offer an inside view of a particular event. Examples include:
Autobiographies, diaries, e-mail, interviews, letters, minutes, news film footage, official records, photographs, raw research data, speeches.
Newspapers can be considered primary sources if they offer first-hand accounts of events. Often they are considered secondary sources.
The Center for Research Libraries (CRL) is an international consortium of university, college, and independent research libraries. UCSD Libraries is a member. As such, UCSD students, faculty, and staff are entitled to borrow materials from there through Interlibrary Loan. The Guides to Materials in the Latin American Materials Project (LAMP) help you identify collections, and often provides guides or finding aids to those collections. In recent years, CRL has begun acquiring resources in electronic format.
